Which value of x must be excluded from the domain of the function, y = 9 / 2(x + 7)?

1 answer:

8 0

B) -7 because the dominator must be different by 0.

2(x + 7) ≠ 0 |divide both sides by 2

x + 7 ≠ 0 |subtract 7 from both sides

x ≠ -7

A company has a cost equation of c=0.925x^2-4x+20 and a profit equation of p=-1.125x^2+6x+40. Solve for the breakeven point.

lana66690 [7]

0.925x^2 - 4x + 20 = -1.125x^2 + 6x + 40 (at break even point)

2.05x^2 - 10x - 20 = 0

x = [ - (-10) +/- sqrt(100 - 4*2.05*-20) / (2*2.05)

x = 6.40, -1.52 Ignore the negative

Answer is 6.40
